Abstract:
Nanocrystalline powder of SiO2, synthesized by gas phase condensation, has been characterized by X-ray and electron diffractometric techniques. The composition of the as-received powder is mostly amorphous and a minor amount of alpha-crystobalite phase. Annealing at higher temperatures, the amorphous phase gradually transforms into small crystallites of alpha-crystobalite. Subsequently, the tiny crystallites form small domains in the structural form of beta-crystobalite.
